Problems with IE8 when running under user rights

When I am logged in with user rights Internet Explorer (version 8 running under XP, SP3) is very slow. It can take tens of seconds to load a page and sometimes IE even hangs. However, when I am logged in with administrator rights everything works fine. How can I get ZA working properly under user rights?
(Note: I know that ZA causes the troubles because when I switch off ZA IE8 also works fine under user rights).

Re: Problems with IE8 when running under user rights

No issue here with the same setup, I would suggest you fully remove your ZAX (XP add/remove a program) and try to reinstall the latest version you find here:

Looking for the latest version? , do not import any previous settings, run at default and test it again. If it fails please contact, free of charge, the ZA technical support at the link in my signature.

Also note that ZA does not support limited user account if implemented via specific group editor policy or ad-hoc programs, only standard/home setup.
